Project description:This SuperSeries is composed of the following subset Series: GSE17757: Gene expression data from primate postnatal brain in prefrontal cortex: time course GSE18012: miRNA expression data from human postnatal brain in prefrontal cortex: time course GSE18013: miRNA expression data from rhesus macaque postnatal brain in prefrontal cortex: time course Refer to individual Series
Project description:Fresh frozen post mortem prefrontal cortex tissue (Brodman area 46) was obtained from 44 individuals varying in age from 0 to 49 years. RNA was extracted from these samples and hybridized to HG133plus2.0 GeneChips. The data was used to examine patterns of gene expression over the course of human postnatal developmental and ageing. PMI - postmortem interval, DLPFC - dorsolateral prefrontal cortex

Project description:To investigate how exposure to morphine during the prenatal and early postnatal period affects the offspring prefrontal cortex in a mouse model We performed gene expression profiling analysis using data obtained from RNA-seq of offspring prefrontal cortical brain samples at postnatal day 21
Project description:While multiple studies have reported the accelerated evolution of brain gene expression in the human lineage, the mechanisms underlying such change remain poorly understood. Here we address this issue from a developmental perspective, by analyzing mRNA and microRNA (miRNA) expression in two brain regions within macaques, chimpanzees and humans throughout their lifespan. We find that developmental profiles of trans-regulators, such as miRNA, as well as their target genes, show the fastest rates of human-specific evolutionary change. Changes in expression of a few key regulators may be a major driving force behind human brain evolution. Human, chimpanzee and rhesus macaque post-mortem brain samples from the prefrontal cortex and cerebellar cortex were collected. The age ranges of the individuals in all three species covered the respective species' postnatal maturation period from infancy to old adulthood. RNA extracted from the dissected tissue was hybridized to B72.
Project description:To unravel the gene expression changes during postnatal prefrontal cortex development, RNA-seq was performed in the rat medial prefrontal cortex at five time points from early life to adulthood (postnatal day 8, 14, 21, 35 and 70) and differential expression of protein-coding genes, lincRNAs and alternative exons was analyzed. A switch from neuronal network development to maintenance during postnatal rat prefrontal cortex development was shown.
